Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UE 4.11 - Show Mouse Cursor breaks mouse coords


UE4.10 (working)

1) Open ShowMouseCursor_4.10 project in zip file


2) Press PLAY, then press any mouse button and move the mouse around


(a) cursor is visible, as expected

(b) mouse coordinates are displayed, as expected




UE4.11 (broken)

3) Open ShowMouseCursor_4.10 in UE4.11

4) Press PLAY, then press any mouse button and move the mouse around


(a) cursor is visible, as expected

(b) mouse coordinates are initially visible,
but as soon as you press any mouse button the mouse coordinates stop being received.

Any blueprint that depends on [Show Mouse Cursor], [GetX] or [GetY] mouse coordinates is broken.

If you uncheck [ ]Show Mouse Cursor (in the level blueprint) then mouse coordinates are received but you'll then have to implement your own custom mouse cursor.

Ok, thanks Rudy. That's weird (UE-28811) because I've been using ShowMouseCursor, GetX, and GetY quiute extensively since 4.6 and never had any problem until I opened my project in 4.11 this morning.

Its a 4.11 bug. Mouse input only works correctly in blueprints if you have the mouse cursor disabled now. Input Axis mouse bindings don't function either while the cursor is shown.

Just wanted to say, awesome work. I converted my card game from 4.10.4 to 4.11 and all of a sudden I need to click a random amount of times in my cards for the click code to run at all. You were of great help to know what my issue was and how to go around it, at least for now. So thanks. Hope they get this fixed in 11.1
